The term was coined by the late D.C. punk
band Minor Threat, who promoted, through their lyrics, a lifestyle free of drugs, alcohol and casual sex. Ian Mackaye, the band's lead, claimed not to have started a movement, however, in today's underground(or not-so-underground) societies of punk
, it has become a full-on label. One who claims "the edge" does not participate in "poisoning" their bodies. No drugs, no alcohol, no casual sex(and others will include veganism
, abstaining from medications, even so far as caffeine, etc). X's are used to represent "the edge".
